The document discusses different types of perspective in drawings. It describes perspective as how our eyes see objects, with perspective drawings containing vanishing points. The three main types of perspective discussed are one-point, two-point, and three-point perspective. One-point perspective contains a single vanishing point on the horizon line. Two-point perspective, which is most commonly used, has two vanishing points on the horizon line. Three-point perspective includes three vanishing points, with two on the horizon line and one above or below. Examples of each perspective type are provided.
